About Converting Markdown to HTML

Markdown is a lightweight plain-text markup syntax that converts cleanly to HTML. It is the standard for README files, documentation and technical writing. When you need to move away from Markdown, the usual reason is simple: limited layout control.

Converting your Markdown document to HTML solves that. HTML is the markup language of the web, describing documents with tags for headings, links, images and structure. Converting to/from HTML bridges web content and office documents. In practice you gain native web format and structured and styleable. PrivConvert runs the whole Markdown-to-HTML conversion in server memory and deletes your file the instant the HTML is ready — nothing is stored, logged or reused.

When this conversion helps

  • You need native web format
  • You need structured and styleable
  • You need universally rendered by browsers
  • Sharing a Markdown document with someone whose software expects HTML

Tips for best results

  • After converting, open the HTML and skim the formatting — complex layouts occasionally need a small touch-up.
  • Files up to 250 MB are supported, and you can batch-convert several Markdown files at once; each is processed privately and deleted immediately.

Frequently Asked Questions

Which Markdown features are supported?
Headings, paragraphs, bold and italic, inline code and fenced code blocks, ordered and unordered lists, blockquotes, horizontal rules, and links.
Is the HTML output safe?
Yes. Every text run is HTML-escaped before formatting is applied, link targets are limited to http(s)/mailto/relative URLs, and javascript: links are dropped - so the result cannot carry injected markup or scripts.
Is it free and private?
Yes. Conversion is free and runs entirely in memory - your file is never written to disk and is deleted the moment your download is ready.
